Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency ten-
sioning devices and belt force limiters.
The ETD is designed to activate in the fol-
lowing cases:
ț in frontal or rear-end impacts exceed-
ing a preset severity level
ț in certain vehicle rollovers
ț if the restraint systems are operational
and functioning correctly, see
1 indicator lamp (
୴ page 56)
In an impact, emergency tensioning devic-
es remove slack from the belts. Belt force
limiters reduce the force exerted by the
seat belts on occupants during a crash.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
ț Secure the child using an infant or child
restraint appropriate to the age and
size of the child and recommended for
use by Mercedes-Benz.
ț Make sure that the infant or child is
properly secured all times while the ve-
hicle is in motion.
Infant and child restraint seats and
information on choosing an appropriate
restraint system can be obtained from any
Mercedes-Benz Center.

The ETDs for the front seats will only
activate if the front seat belts are fas-
tened (latch plate properly inserted
into buckle).
The ETDs for the rear outer seats will
activate with or without the respective
seat belts fastened.
Warning! G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at your autho-
rized Mercedes-Benz Center.
